I take heed to VHF radio when in Savannah, Georgia, to get climate forecasts for the Atlantic Ocean. They typically say waves 2-four ft close to shore and 5-eight ft nicely offshore. What is taken into account nicely offshore?

Coastal marine forecasts alongside the Atlantic Ocean prolong 50 miles outward. Wave heights typically differ significantly in so giant an space. The precise break between close to shore and nicely offshore is on the forecaster’s discretion, however properly offshore means close to the 50-mile restrict. The boundary for the a lot smaller Nice Lakes between close to shore and open water is about at 5 miles. Nearshore marine forecasts from the Nationwide Climate Service cowl winds, waves and climate out to 5 miles spanning the subsequent three 12-hour durations. Wave forecasts for the Nice Lakes aren’t damaged into close to shore and properly offshore.
For forecasts alongside the Atlantic, properly offshore means close to a 50-mile restrict. Wave forecasts for the Nice Lakes are usually not damaged into close to shore and properly offshore.
